JDM ecu Vs. OEM ecu

What diffrence do they have? I took out the Oem ecu and dropped in the JDM ecu, it has a little improvements but now I have the MIL on. Its on a 94 Civic, but i got the ecu from a 91 Civic hatch. w/ a JDM D15B engine. What is better in performance?

Dude, the 94 is OBD-1, the ecu you put in is not, thats why your getting those codes...Or im a noob, probably the latter.

well dude tell me why the JDM ecu fits into a male connector from a obd 1 wire harness, obviously a obd 0 ecu will not fit a obd 1 connector.
JDM D15B is OBD 1do a litlle research.

You havnt been here long enough to be a cocky little bitch yet. Sit down.

Now can you accually prove it made more power or is this just a butt dyno? Poeple offen think things make differnces when they really do not, sometimes it may even be slower but they notice a change and think its faster. Whats the ecu code? Most people that do the d15b swap dont use a jdm ecu.

hey look at the noob gettin all cocky and expects us to help him when he doesn't even tell what ecu he is even using. wow. amazing. the people these days all want help, then when you try to give it to em they get all angry wit you.:nono:

:nono: look... im not cocky, and only because i have no stars and called a newbie because i dont live my life on the internet does not mean that i do not know what im doing. I was just wondering what the difference between a
OEM PM5 ecu and a JDM P08 ecu would be that was all, this website is full of information and i respect it, also respect all of you guys that share it with other newbies like myself. Thanx for your help.:smooch:

so you tryin to say i live my life on the internet! i'll have you know i work 16 hour days to keep you safe in this country! you wanna come do my job! I gave up everything for people like you, then i try to help you, but you don't give all the info, then get angry and cocky telling us to do research! then don't expect good help! remember you asked for our help! don't tell us to do research i've been working on F$%^ing hondas since I was 10!!!

THIS SHOULD HAVE BEEN YOUR FIRST QUESTION!!!

a p08 is basically a p28. go buy one of those! they're better.

Look men i did not tell youto do some research i was to talking to the kid who answered my question, and i appreciate you for keeping this country safe and god bless you an the rest of the troops. This is funny, a question turns to an argument, whatever, i got better things to worry about, just forget it. you win

we'll essentially a p08 is a p28. i would say it to better to buy a p28 then chip than to go with a p08. chipping a p28 is really easy, all ya need is a zif socket and a lil other things. good luck with your car.

sorry 'bout the arguement, but i ain't sleeped since i got off work. so nite ya'll

You're confused about one of the years, either the year of the car or the year of the ECU that you are running. The plugs from OBD-0 ('91 or older) and OBD1 ('92-'95) are completely different. If you do infact have a '94 Civic, then you must be using an OBD1 ecu; there is NO way around it. Here's what the ecu commections look like on an OBD0 ('91) ecu: http://www.ff-squad.com/tech/wiring/wiring.88-91.jpg Here is what they look like for an OBD1 ('94) ecu: http://technet.ff-squad.com/wiring/obd1/plugs2.jpg
Pull the ECU code to find it out, do a search online if you don't know how to do that.

i'm wondering if it's kinda like the pr3 ecu's. ya know there were both obd-0 and obd-1. he probably just got the car year messed up.

Well if it's the PM5, then that's an OBD0 only ecu. There are very few ecu's that keep the ecu code from one obd to another.

Wow..so I was right, I dont feel like such a jackass anymore (although I am :P).

i need some help i need to know what wolud be good to drop in my car b16 or a zc moter

hey you might wanna use the search option or make your own post.
crazy post hijacking noob. lol
